RESEARCH PROJECTS HIGHLIGHT

My area of research focuses on plant interactions with their pathogens with an especial focus on the interactions with insect pests. In addition, studies on insect pest prevalence and abundance, along with population genetic analysis will help provide the best strategies for pest elimination. By conducting studies that examine plant gene expression changes I hope to not only elucidate signaling mechanisms used by plants during defense reactions but also to identify genes to be used to in protecting plants from the stresses of pathogen attacks. These genes may come from wild relatives or other species. One specific plant pest that is of interest is whiteflies. These phloem feeding insects remove photoassimilates along with vectoring viruses. The long term goal of experiments will be to breed and create plant germplasm that is resistant to or tolerant of these devastating pests.
